摘要： A Voltage Controlled Oscillator (VCO) with the ability to tune its operating frequency over a wide range using a limited control voltage range. The VCO implements a novel resonant circuit that provides the wide frequency tuning range and simultaneously provides increased immunity to induced low frequency noise. The resonant circuit utilizes an element configuration that includes high pass filters (402, 422 and 404, 424) on each input to the resonant circuit. Varactor diodes (432, 434) are used to couple a conventional tuning circuit to the remainder of the resonant circuit. This configuration allows the resonant frequency to tune over a wide range using a limited control voltage range.

摘要： Features and advantages of the present disclosure include a multimode voltage controlled oscillator (VCO). In one embodiment, a circuit comprises a VCO, first and second transistors, and first and second capacitive attenuators. The first and second transistors are cross coupled through the attenuators. In a first mode, the first and second transistors are turned off, and the capacitive attenuators attenuate a signal on output terminals of the VCO at control inputs of the first and second transistors. In another mode, the first and second transistors are turned on, and the capacitive attenuation is reduced or turned off so that control inputs of the first and second transistors receive signals on the outputs of the VCO.

摘要： A novel and useful 60 GHz frequency generator based on a third harmonic extraction technique which improves system level efficiency and performance. The frequency generator employs a third harmonic boosting technique to increase the third harmonic at the output of the oscillator. The oscillator generates both ~20 GHz fundamental and a significant amount of the third harmonic at ~60 GHz and avoids the need for a frequency divider operating at 60 GHz. The undesired fundamental harmonic at ~20 GHz is rejected by the good fundamental HRR inherent in the oscillator buffer stage while the ~60 GHz component is amplified to the output. The fundamental harmonic is further suppressed by an active cancellation by properly combining the two outputs. The oscillator fabricated in 40nm CMOS exhibits a phase noise of -100 dBc/Hz at 1 MHz offset from a 60 GHz carrier and have a tuning range of 25%.

摘要： A method for calibrating an oscillator in an electronic device and an electronic device configured for calibration are provided. Multiple signals are sent to the electronic device from another electronic device, such as from a host device. With knowledge of the time interval between the multiple signals, the electronic device may calibrate the oscillator in the electronic device. For example, the electronic device may be a USB-compliant electronic device. The USB-compliant electronic device may receive Start of Frame (SoF) signals from a host device, which in one USB implementation is received at 1 mSec intervals. The USB-compliant electronic device may count the output of the oscillator between receipt of different SoF signals in order to determine the frequency of the oscillator at different oscillator settings.

摘要： An electronic device has a capacitive arrangement (100) for controlling a frequency characteristic. The capacitive arrangement has varactor banks having a number of parallel coupled varactors and a control input for switching the respective varactors on or off. A main varactor bank (110) has N varactors and a series varactor bank (120) has A varactors, the main varactor bank being connected in series with the series varactor bank. A shunt varactor bank (130) of B varactors may be coupled to a ground reference and connected between the main varactor bank and the series varactor bank, When a varactor is switched in the main varactor bank, it provides an equivalent capacitance step size (or frequency step) smaller than size of a capacitance step when switching a single varactor on or off. According to the number of varactors selected in the shunt varactor, B, this frequency step can be made programmable. By the arrangement of unitary varactors a very small step size is achieved for providing a high resolution of frequency of a digitally controlled oscillator.

摘要： Capacitive adjustment in an RCL resonant circuit is typically performed by adjusting a DC voltage being applied to one side of the capacitor. One side of the capacitor is usually connected to either the output node or the gate of a regenerative circuit in an RCL resonant circuit. The capacitance loading the resonant circuit becomes a function of the DC voltage and the AC sinusoidal signal generated by the resonant circuit. By capacitively coupling both nodes of the capacitor, a DC voltage can control the value of the capacitor over the full swing of the output waveform. In addition, instead of the RCL resonant circuit driving a single differential function loading the outputs, each output drives an independent single ended function; thereby providing two simultaneous operations being determined in place of the one differential function.

摘要： Apparatus and methods for distributing spurious tones through the frequency domain are disclosed. One such apparatus can include a dithering circuit configured to generate a sequence of numbers that exhibit statistical randomness and a variable frequency circuit configured to adjust a frequency of an output based on the sequence of numbers so as to spread energy of spurious tones in a frequency response of the output to lower a noise floor. In one example, spurious tones can be reduced in a negative voltage generator of a radio frequency (RF) attenuator.
